[SPARK-14386][ML] Changed spark.ml ensemble trees methods to return concrete types
## What changes were proposed in this pull request?
In spark.ml, GBT and RandomForest expose the trait DecisionTreeModel in the trees method, but they should not since it is a private trait (and not ready to be made public). It will also be more useful to users if we return the concrete types.
This PR: return concrete types
The MIMA checks appear to be OK with this change.
## How was this patch tested?
Existing unit tests
